  • Description

    JW®3311 is a multi-cell battery protection IC that includes high-accuracy voltage detection circuits and delay circuits. It is possible for users to monitor the status of 8~10 series cell lithium-ion rechargeable battery pack. 

    JW3311 provides multiple protect functions including over-charge, over-discharge, over-current, over-temperature and open wire detection. More JW3311s can operate in cascade to protect long string battery.
